What Pure Water & Nature Technologies does

Pure Water & Nature Technologies (PWNT), legally PWNT Holding B.V., is a Netherlands-headquartered water-technology business and an innovation center within Nijhuis Saur Industries (NSI), the water arm of the Saur Group. PWNT designs, engineers and delivers modular drinking-water treatment systems to municipal and national water utilities, built around three proprietary technology platforms: SIX® (Suspended Ion Exchange) for removing natural organic matter, dissolved organics and micropollutants; ILCA® (In-Line Coagulation and Adsorption) for compact pre-treatment optimization; and CeraMac® (Ceramic Membrane Filtration), a robust, modular membrane solution. The technologies are field-proven through full-scale reference plants including Andijk III (Netherlands, 120 MLD), Choa Chu Kang (Singapore, world's largest ceramic membrane system), Mayflower (UK, ~250,000 residents served), Sonnenberg (Switzerland), Bonnycraig (Scotland) and Witches Oak (England, 89 MLD).

PWNT generates revenue through two streams: (1) one-time sale of treatment systems, equipment packages and plant infrastructure for full-scale municipal projects, and (2) consultancy and technical services covering pilot studies, validation and operational support across the project lifecycle. Pricing is project-based, bespoke and quote-driven; no list pricing is disclosed. The go-to-market is exclusively direct enterprise field sales, executed through NSI's eight regional centers spanning Benelux & DACH, France, Central Europe, UK & Ireland, Central Asia, Americas, Middle East & Africa, and Asia Pacific, providing local implementation support alongside global technology delivery. All named customers are government or state-owned utilities.

Core offering

PWNT designs, engineers, and delivers advanced modular drinking water treatment technologies (SIX® suspended ion exchange, ILCA® in-line coagulation and adsorption, and CeraMac® ceramic membrane filtration) as scalable systems to municipal water utilities. The company also provides water consultancy services including pilot studies, full-scale validation, and operational support across the project lifecycle.

Product overview

Pure Water & Nature Technologies (PWNT) offers a modular portfolio of three advanced water treatment technologies developed for drinking water utilities. The portfolio consists of SIX® (Suspended Ion Exchange) for removing organic matter and dissolved contaminants, ILCA® (In-Line Coagulation and Adsorption) for compact pre-treatment optimization, and CeraMac® (Ceramic Membrane Filtration) for high-performance membrane filtration. These technologies can be deployed individually or in combination to address a wide variety of source water conditions and treatment goals.

Direct peers

• Organo Corporation: Japanese water treatment specialist with municipal and industrial customers using ion exchange, membrane, and adsorption technologies — directly comparable technology stack to PWNT's SIX®, ILCA®, and CeraMac® combination.
• Metawater: Japanese water treatment company specializing in ceramic membrane filtration and ozone-based systems for municipal water utilities — the closest direct competitor to PWNT's CeraMac® offering, with comparable reference projects and target customers.

Broad incumbents

• De Nora: Italian multinational with a water technologies segment offering filtration, disinfection, and electrochemical solutions to municipal water and wastewater utilities. Comparable end-market and project scale to PWNT.
• Suez Water Technologies & Solutions: Large incumbent serving municipal drinking water and industrial water treatment markets with filtration, disinfection, and process technologies. Overlaps with PWNT in municipal source-water treatment and competes on full-scale plant deliveries.
• Veolia Water Technologies: Global water and wastewater treatment major with broad municipal and industrial offerings including filtration and advanced treatment. Competes with PWNT on large municipal tenders but as one of many capabilities in a much wider portfolio.
• Xylem: Global water technology company offering treatment, filtration, and pumping solutions to municipal utilities. Competitor in the broader drinking water treatment market though Xylem's portfolio is broader than PWNT's focused ceramic membrane + ion exchange stack.
• Hitachi Industrial (Water & Infrastructure): Japanese conglomerate with a water and infrastructure business delivering advanced treatment systems to municipal utilities. Comparable in serving large municipal projects with integrated water treatment technology stacks.
• Kurita Water Industries: Japanese water treatment major supplying treatment chemicals, equipment, and ultrapure/process water systems to municipal and industrial customers. Comparable in serving utilities with advanced treatment solutions, though with a chemicals-heavy approach.

Emerging players

• Cembrane: Danish specialist in ceramic membrane technology for water and wastewater treatment. Closest head-to-head technology competitor to PWNT's CeraMac® in the European municipal market, though at smaller scale.
• Pall Corporation (Cytiva): Membrane and filtration manufacturer with significant municipal and industrial water applications. Overlaps with PWNT on the membrane side and increasingly competes on advanced water treatment, though Pall's center of gravity is industrial/life sciences.
